Become Luna's pimp
From Create Your Own Story
"You've done well Today Luna. I really think you could make some money out of this but you know what would really bring in the galleons? If you had a manager. Think about it I'll arrange your appointments, vet the clients and give you a place to conduct your business in private. For a small fee of course."
Harry looked at Luna. He knew she would agree the spell would make sure of it. He didn't know how he knew that but after he cast the spell he had a vague understanding of how it worked. When cast on a girl it would basically turn her into his slave. Sex slave specifically but that was splitting hairs.
"Oh yes Harry. That sounds wonderful. You took such good care of me today, I want you to look after me from now on."
Harry grinned, she had just given him permission to whore her out for his own profit. Of course he would take the time to sample the goods occasionally it that was just a perk of the job.
"All right Luna get dressed, we've got work to do."
After taking his time watching Luna put her skimpy outfit back on harry soon dressed himself and checked out of his room. Walking through the cauldron and out into Diagon Alley he made his way towards Gringots. Quickly he withdraw all of the money in his vault, which he hoped should be enough to get his business going.
"What are you going to do with all that money Harry?"
Harry turned to Luna struggling to look her in her eyes as her chest bounced around in her revealing top.
"Well, we'll need a place to work from won't we. I think I know just the place."
Harry strode towards the end of Diagon Alley where it ran into Nocturn Road. A building that was just on the edge. No one walked here unless they were up to some illicit business but if you were caught you could still say you were in Diagon Alley.
"This will be the perfect place for us Luna. We've got the foot traffic from the alley and the morals from the road. We will be selling your body in no time."
After purchasing the building, amazing how quick cash makes things. They set about getting the place ready. A charm was set up so that anyone that was interested in what they were selling (Luna) would be able to tell the purpose of the building but everyone else would just see an ordinary residence. After a few days the place was pretty much ready to go.
"Good work Luna. I think it's time we made some money."
